ECOS Interior/Exterior Wood Primer is a unique resin technology that's both non-toxic and zero VOC; it's safe for everyone. It's an architectural coating made specifically for unfinished bare woodwork indoors or outdoors such as trim, furniture, doors, windows, etc. ECOS Interior/Exterior Wood Primer is made without solvents or hazardous chemicals, and it contains no biocides or fungicides.
Compared to the ECOS Universal Primer, this is best for raw wood. It will seal knots and tannins well and provide a good foundation for paint. It's not recommended for oily exotic woods, such as ebony and teak. For previously painted surfaces we recommend ECOS Universal Primer.
ECOS Wood Primer applies with brush, roller or spray, leaving a beautiful smooth, even finish. One thing that makes ECOS unique is its coverage; one gallon covers 460-520 SF per coat.
ECOS has industry-leading test performance and accreditations:
The first North American paint manufacturer to complete the Health Product Declaration (HPD) — an open-standard format for accurate, reliable and transparent reporting of product contents for LEED v4 that requires third-party certification;
The only paint manufacturer with Declare Labels showing LBC Red List Free (a transparent ingredients labeling tool developed by the Living Building Challenge for manufacturers to fully disclose all intentionally added ingredients; Red List is a collection of worst-in-class building materials);
The only professional-grade paint and primer certified to ASTM D-4236 (non-toxic);
The only paint company with membership in the Juvenile Products Manufacturer’s Association (JPMA);
The only paint company approved by the national non-profit Healthy Child Healthy World
See right hand margin for downloadable PDFs including MSDS (Material Safety Data Sheet), HPD, Declare label, CDPH (Calif Dept. Pub. Health), ASTM D6886 (VOC test results) and application instructions.
Sample sizes (2 oz) are available for $9.95 including shipping. Swatch decks are also available.
While ECOS Universal Primer can also be used for woodwork, this product is more specialized in its ability to seal knots and resins from leaching out. It's an excellent non-toxic alternative to traditional wood primers.

Application Temperature Range
DO NOT THIN. Stir gently and thoroughly before use. Apply one coat to bare wood and allow to dry for at least 6 hours before over-coating. Normally touch dry in 1-2 hours. Avoid applying below 41°F (5°C). Clean equipment and brushes with water.
Surface or Product Preperation
Ensure that woodwork is sound, smooth, dry and free of dust, dirt and grease. Knots should be treated with ECOS White Knotting Compound. Fillers should be sealed with ECOS Filler Sealer. Bare hardwoods - Ask for advice. WARNING: Older buildings may contain lead-based paint, which requires professional remediation if it is disturbed. If in doubt, consult with a professional from a Lead-Safe Certified Firm.
